Barton's four RBIs back Cahill's 10 K's as A's blank Pirates

OAKLAND, Calif. -- Trevor Cahill hasn't allowed himself to think about his All-Star status. After opening the season on the disabled list, he wasn't sure he'd even be back in Oakland. These days he's the staff ace.

Cahill allowed two hits and struck out a career-high 10 in 7 2/3 innings and Daric Barton had three doubles and matched his career high with four RBIs and the Athletics earned a 5-0 victory over the Pittsburgh Pirates on Saturday night.

Cahill (7-2) walked three as the A's won two in a row for the first time since winning four straight May 26-29.

"A couple of months ago, when I was in Las Vegas and Sacramento I never thought I'd here," said Cahill, who had a stress reaction in his right shoulder toward the end of spring training. "It's an honor just to be considered. We have plenty of guys good enough to be named."

Cahill improved to 5-0 over his past eight starts and has lowered his ERA to 2.88. He's allowed 13 earned runs over his past 50 1/3 innings.

"The biggest thing is just going out there with confidence," Cahill said. "I was able to locate the sinker and go in and out to both right-handers and left-handers."

Kurt Suzuki homered as the A's remained unbeaten in eight games against the Pirates.

"I'm still trying to find my groove," Suzuki said. "I'm not worried about results right now. It's more able how I feel in the box. Right now I'm not as comfortable as I want to be."

Daniel McCutchen (0-3), recalled earlier in the day to replace Zach Duke, lasted six innings. He gave up four runs and seven hits, walking two and striking out two.

"Early on I had some jitters and some nerves," McCutchen said. "I kind of sped everything up and didn't give myself a chance the first couple of innings. It's something to build off of. It would have been a whole different game if I was able to get strike one with the fastball. Pitching behind in the count I was forced to throw too many fastballs."

Pirates manager John Russell felt McCutchen did some good things.

"He did OK," Russell said. "He'd get two quick outs and had trouble putting them away. Two-out hits and two-out runs."

The Pirates lost their 16th consecutive road game, their second-longest streak in the past 25 years, and have lost 17 of 19 overall.

"We've been hitting pretty good overall but we haven't been able to outscore the other team," Pirates first baseman Garrett Jones said. "Today he was on. He was hitting his spots and he had good stuff. We never got much to hit."

Coco Crisp singled twice, walked and scored three runs and is hitting .438 since coming off the disabled list Tuesday.

It was 1970s Turn Back the Clock Game with both teams wearing flashy uniforms from the 70s, with the A's in bright yellow and green and the Pirates in black and gold. Pittsburgh even dusted off its famed pillbox caps. The Pirates and A's were dominant teams in the 70s, combining for five World Series titles.

Barton had an RBI double in the first, a two-run double in the second and another run-scoring double in the seventh.

"Coco has been getting on base a lot and it's helpful to me," Barton said. "I get a lot of pitches to hit and I'm slowing everything down."

Suzuki hit his ninth home run of the season in the fifth, a solo shot with two outs.
